[0001] The utility model relates to the technical field of fire monitors, in particular to a mobile fire extinguishing monitor. Background Art

[0002] Fire monitors are important firefighting equipment for long-distance fire fighting. Fire monitors are divided into two series: fire water monitors and fire foam monitors. Fire water monitors are firefighting equipment that sprays water to extinguish general solid materials at a long distance. They are more common in fire brigades at this stage.

[0003] After searching, the existing Chinese patent publication number is CN215025581U. This utility model provides a mobile fire-fighting cannon device for firefighting engineering, including a base, the upper surface of which is provided with a fixing groove, the inner wall of which is rotatably connected to a support column via a bearing, the top of which is mounted with a C-shaped frame, the left and right inner walls of which are rotatably connected to limit rods, the opposite ends of the two limit rods are mounted with the fire cannon body via a mounting plate, and the surfaces of the two limit rods are fixedly connected to a first gear, and a through hole is provided on the right side of the C-shaped frame. By providing a base, a support column, a C-shaped frame, a limit rod, a first gear, a fixing rod, a second gear, a rotating plate, and a limit pin, the device facilitates 360-degree full-range angle adjustment of the fire cannon, can quickly aim the fire cannon at the fire area, and does not require manual handling, reducing the risk of firefighters holding the cannon by hand, facilitating angle adjustment, and improving firefighting efficiency.

[0004] However, in the above technology, in order to avoid the fire water cannon being displaced by recoil when spraying water to extinguish fire, a plurality of support frames are usually provided on the base to increase the contact area between the base of the device and the ground and increase the stability of the device. However, when placing and retracting the support frames, each support leg needs to be operated separately. The process is relatively inconvenient and cannot be quickly retracted and released, which is not conducive to the timely implementation of firefighting work. A solution is proposed to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to make up for the above shortcomings, the present invention provides a mobile fire-fighting cannon, which aims to improve the problem that the fire-fighting water cannon is usually equipped with multiple support frames on the base to avoid the recoil causing the fire-fighting water cannon to shift when spraying water to extinguish fires, so as to increase the contact area between the base of the device and the ground and increase the stability of the device. However, when placing and retracting the support frames, each support leg needs to be operated separately, which is a relatively inconvenient process and cannot be quickly retracted and deployed, which is not conducive to the timely implementation of firefighting work.

When the connecting piece moves downward, the connecting rod fixed with it will rotate with the end point of the support rod as the center of the circle, and its push rod will gradually move away from the side of the support plate as the No. 1 hydraulic cylinder extends. Then the reset spring will contract and cause the originally vertical support plate to rotate to a horizontal state. The bottom of the support plate will continue to extend with the No. 1 hydraulic cylinder until it touches the ground and supports the rear of the device. At this time, fire extinguishing work can be carried out. When retracting the support plate, the No. 1 hydraulic cylinder can be retracted. The push rod set on the side of the No. 1 hydraulic cylinder will gradually retract and touch the side of the support plate, forcing the horizontal support plate to return to a vertical state.

[0014] Preferably, the bottoms of two of the sliders are respectively threadedly connected to the two sides of the bidirectional screw rod, and the bottoms of the other two sliders are respectively slidably connected to the two sides of the slide rod.

[0015] As a further description of the above technical solution: the other two sliders can separate or gather from each other when the bidirectional screw rod rotates, so as to play the role of raising or lowering the fire monitor.

[0016] Preferably, the upper end of the mounting plate is fixedly connected to a support frame, and the upper end of the support frame is rotatably connected to a fire monitor.

[0017] As a further description of the above technical solution: the support member can be used to install a fire monitor.

[0018] Preferably, the upper end of the mounting plate is rotatably connected to a No. 2 hydraulic cylinder, and the output end of the No. 2 hydraulic cylinder is rotatably connected to the lower end of the fire monitor.

By this method, the device can quickly complete the adjustment work of the support legs of the device when it is needed to extinguish the fire, greatly shortening the time for preparation work before fire fighting and improving the fire fighting efficiency.

[0024] 2. In the present invention, when the height and angle of the fire monitor need to be adjusted according to different environments, the motor can be started, and the motor can drive the bidirectional screw to rotate. The rotating bidirectional screw will drive the sliders on both sides to separate to both sides, and push the lifting rod to move and rotate when separating, so that the other end of the lifting rod will move upward to raise the height of the mounting plate, and then the height of the fire monitor can be adjusted. At the same time, the No. 2 hydraulic cylinder can be started, and the inclination angle of the fire monitor can be adjusted by extending and retracting the No. 2 hydraulic cylinder. This method allows the device to adapt to various fire extinguishing needs in different environments by adjusting its own angle when performing firefighting work. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] When the fire monitor 6 needs to be used for fire extinguishing, the No. 1 hydraulic cylinder 13 can be started to extend and the connecting member 15 can be pushed down. When the connecting member 15 moves down, the connecting rod 16 fixed thereto will rotate with the end point of the support rod 11 as the center of the circle, and its push rod 14 will gradually move away from the side of the support plate 10 as the No. 1 hydraulic cylinder 13 extends. Then the return spring 17 will contract and cause the originally vertical support plate 10 to rotate to a horizontal state.

At this time, fire extinguishing work can be carried out. When retracting the support plate 10, the No. 1 hydraulic cylinder 13 can be retracted. The push rod 14 set on the side of the No. 1 hydraulic cylinder 13 will gradually retract and contact the side of the support plate 10, forcing the horizontal support plate 10 to return to a vertical state. This method allows the device to quickly complete the adjustment of the device support legs when fire extinguishing work is needed, greatly shortening the time for pre-fire preparation work and improving firefighting efficiency.
